getPageByName not working.

[brunoreis]

I was studying the (very good by the way) Tutorial on Creating a Tag Board.
I created the piece to work before form to chose the right page. But It did not work, the method getPageByName did not exist.

So I found that there is a ff_getPageByName and even that I need to call

Code:

$this->execPieceByName('ff_InitLib');

to make it work. There were no more error messages, but it did not worked either... then I put some echos on the script:

Code:

echo "@1<br>";flush();
$this->execPieceByName('ff_InitLib');
echo "@2<br>";flush();
global $my, $exists;
$exists = 0;
//look through the tables to see if mos_tbd_tags is in the Mambo database.
$dataset = mysql_query('SHOW TABLES') ;
while( $row = mysql_fetch_row($dataset) )
{
if ( $row[0] == "mos_tbd_tags" ) {
$exists = 1;
break;
}
}
echo "exists=='".$exists."'<br>";
// if it exists got to page 1
if ( $exists == 1 ) {
        echo "@3<br>";flush();
$this->page = ff_getPageByName($this, 'ftb_intro');
// if it does not exist send the form to the correct page for user type
 } else {
if ($my->usertype == "superadministrator") {
                echo "@4<br>";flush();
$this->page = ff_getPageByName($this,'ftb_ctable');
} else {
                echo "@5<br>";flush();
$this->page = ff_getPageByName($this,'ftb_ntable');
}
}
echo "page=='".$this->page."'<br>";flush();

but looking at the form all I got was...

@1
@2
exists=='0'
@5
page==''

that means that the ff_getPageByName($this,'ftb_ntable'); did not return anithing.
But on page 3 I do have the following item:
    No Table     ftb_ntable     Static Text/HTML                    10px     0px     160

What is wrong?
Is there another way to use getPageByName?

try ff_getPageByName('thename')

It did not work. It did not returned the page number.

Is this the right use of this method: return the page where an element of a form is ?

Of course if I put

$this->page = 3

it will work, but

$this->page = ff_getPageByName('ftb_ntable');

won´t.

Please help me on that since this looks like a good method to be used.

I checked it, and it apprears to be a bug in the piece library. Obviously not a too heavy used function because it was not reported since last november

Anyway, here is how you can fix it:

• Click Manage Pieces
• From the Package drop down select FF
• Click on Get page # by element name
• Add the global declaration for $ff_processor so the function looks as below
• Save the piece

Code:

function ff_getPageByName($name)
{
    global $ff_processor;
    foreach($ff_processor->rows as $row)
        if ($row->name==$name)
            return $row->page;
    return null;
} // ff_getPageByName

Now it is ok. It worked just fine.

Thank for the help.

* by the way, I put a post on the tutorial linking to this topic.

Hi,

I am trying the Tutorial but have got stuck at this point. I have added the 'global $ff_processor;' to the function still without luck.

One strange thing though is that the function name in the Piece Library is called ff_getPageByNameX (with an X at the end). I did not change this, it comes installed named this way...

I am using version 1.4.4, please someone help me get past this bug.

Alain.
